具体的，两步随机接入包括：
消息A(Message A，MSG A)。由终端发送给网络侧设备。
消息B(Message B，MSG B)。由网络侧设备发送给终端。
具体的，上述MSG 1是前导码Preamble；MSG 2是随机接入响应(Random Access Response,RAR)；MSG 3是上行传输，可以包括RRC建立请求、RRC恢复请求、RRC重建请求、上行数据传输中的至少一个；MSG 4可以包括竞争冲突解决、RRC建立消息、RRC恢复消息、RRC重建消息中的至少一个。
在两步随机接入中，MSG A包含MSG 1和MSG 3，网络侧为终端的MSG1及MSG 3配置一个时频资源。由于MSG 1是基于竞争的，所以导致MSG A也是基于竞争的。由此带来的问题是，如果MSG1冲突，将导致MSG 3也冲突，从而导致终端无法解调出MSG 3。因此，如何提高MSG 3的解调概率是亟需解决的关键问题。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
如图1所示，本公开实施例提供一种随机接入的资源配置方法，应用于网络侧设备，包括：
步骤11，向终端发送第一配置信息，所述第一配置信息为随机接入的第一消息的第一配置信息，所述第一消息包括：前导码和载荷；
所述第一配置信息用于配置发送所述前导码的至少一个第一资源以及与每个第一资源分别对应的、用于发送所述载荷的至少一个第二资源。
所述第一消息还可以是消息A(Message A,MSG A)。
所述的第一消息中的前导码，还可以是Preamble，或消息1(Message 1,MSG 1)；所述第一消息中的载荷，还可以是消息3(Message 3,MSG 3)，载荷中可以包含UE ID(终端标识)、连接建立请求、连接恢复请求、连接重建请求、数据包中至少之一。其中UE ID可以是恢复ID(即resume id)，也可以是生成的随机数，也可以是TMSI，或S-TMSI，或ng-5G-S-TMSI的一部分，或GUTI，或C-RNTI等终端标识。
具体的，所述至少一个第一资源，可以是将前导码(Preamble)分成多组，每组作为一个第一资源，例如60个前导码，分成60组，每组包含1个前导码。所述至少一个第二资源，可以是对于每个前导码分组，都对应多个第二资源，所述第二资源用于发送载荷，例如，1个前导码对应5个第二资源。再例如，第一配置信息中，为终端配置用于前导码发送的N组前导码资源，为每组前导码资源都配备若干个用于发送载荷的第二资源。
网络侧设备可以通过广播消息发送上述第一配置信息，也可以通过专用消息(例如RRC重配消息)向终端发送所述第一配置信息。
可选的，每个第一资源包括下述至少之一：
至少一个前导码preamble；
发送所述前导码的时频资源；
用于标识发送所述前导码的时频资源的用于随机接入的无线网络临时标识(Random Access-Radio Network Temporary Identity，RA-RNTI)。
例如，网络侧设备向终端发送第一配置信息，第一配置信息中包含若干前导码和若干时频资源，任意一个前导码和任意一个时频资源构成一个第一资源；第一配置信息中还包含与每个第一资源对应的至少一个第二资源。
需要说明的是，当第一配置信息针对基于非竞争的随机接入的情况下，与每个第一资源分别对应的第二资源的数量大于或者等于1个即可；而当第一配置信息针对基于竞争的随机接入的情况下，与每个第一资源分别对应的第二资源的数量需大于或者等于2个。
由于非竞争随机接入是预留的资源，所以不会冲突。而对于竞争的随机接入，网络侧会为每组第一资源配置对应的至少两个第二资源，以减少上行传输资源冲突的概率。
作为一个可选实施例，所述方法还包括：
向终端发送第二配置信息，所述第二配置信息为随机接入的第二消息的第二配置信息，所述第二消息包括：随机接入的消息B(即MSG B)，或随机接入的消息2(即MSG 2)，或随机接入的消息4(即MSG4)，或随机接入响应；
所述第二配置信息用于配置接收所述第二消息的响应窗和/或第三资源。
所述消息B，即为MSG B(Message B)，是两步随机接入的第二条消息。
所述消息2，即为MSG 2(Message 2)，是四步随机接入的第二条消息，或者两步随机接入的第二条消息的一部分，或两步随机接入回退四步随机接入的第二条消息。
所述随机接入响应，即为RAR(Random Access Response)。
需要说明的是，MSG2和/或MSG4构成两步随机接入的MSG B。上述MSG2是随机接入响应RAR；MSG4是竞争冲突解决消息或连接建立完成消息(如RRC建立消息、或RRC恢复消息、或RRC重建消息)。
例如，网络侧设备向终端发送第二配置信息，配置与每个第二资源对应 的响应窗和/或第三资源。
进一步需要说明的是，上述接收第二消息的响应窗和/或第三资源与发送载荷的第二资源对应。例如，终端在第一个第二资源上发送载荷，则终端在与第一个第二资源对应的第一响应窗和/或第三资源上接收第二消息(MSG B或MSG 2)；再例如，终端在第二个第二资源上发送载荷，则终端在与第二个第二资源对应的第二响应窗和/或第三资源上接收第二消息(MSG B或MSG 2)。
综上，本公开的上述实施例通过为前导码的每组资源配置与其对应的载荷的多个资源，使得即使前导码发生冲突，网络侧也可以通过载荷的多个资源区分来自不同终端的消息A，提高载荷的解调概率以及终端的接入概率；同时MSG B的接收窗口是与MGS 3相对应的，可以最大程度避免MSG B的冲突。
如图2所示，本公开实施例还提供一种随机接入方法，应用于终端，包括：
步骤21，接收网络侧设备发送的第一配置信息，所述第一配置信息为随机接入的第一消息的第一配置信息，所述第一消息包括：前导码和载荷；
所述第一配置信息用于配置发送所述前导码的至少一个第一资源以及与每个第一资源分别对应的、用于发送所述载荷的至少一个第二资源。
所述第一消息还可以是消息A(Message A，MSG A)。
所述的第一消息中的前导码，还可以是Preamble，或消息1(Message 1，MSG 1)；所述第一消息中的载荷，还可以是消息3(Message 3,MSG 3)，载荷中可以包含终端标识(UE ID)、连接建立请求、连接恢复请求、连接重建请求、数据包中至少之一。其中UE ID可以是恢复ID(即resume id)，也可以是生成的随机数，也可以是TMSI，或S-TMSI，或ng-5G-S-TMSI的一部分，或GUTI，或C-RNTI等终端标识。
具体的，所述至少一个第一资源，可以是将前导码(Preamble)分成多组，每组作为一个第一资源。所述至少一个第二资源，可以是对于每个前导码分组，都对应多个第二资源，所述第二资源用于发送载荷。例如，第一配置信息中为终端配置用于前导码发送的N组前导码资源，为每组前导码资源 都配备若干个用于发送载荷的第二资源。
进一步的，本公开的上述实施例中，所述方法还包括：
所述终端从至少一个第一资源中选择一个第一资源发送所述前导码并从所选择的一个第一资源对应的至少一个第二资源中选择一个第二资源发送所述载荷。
简言之，终端发送MSG A的方法是：在第一资源中选择一个资源发送preamble，随后在选择的一组第一资源相对应的M个第二资源中选取一个第二资源发送载荷。选取第二资源的方式可以是随机选取，也可以是按照某一预设规则选取，在此不做具体限定。
可选的，每个第一资源包括下述至少之一：
至少一个前导码；
发送所述前导码的时频资源；
用于标识发送所述前导码的时频资源的RA-RNTI。

需要说明的是，当第一配置信息针对基于非竞争的随机接入的情况下，与每个第一资源分别对应的第二资源的数量大于或者等于1个即可；而当第一配置信息针对基于竞争的随机接入的情况下，与每个第一资源分别对应的第二资源的数量需大于或者等于2个。
由于非竞争随机接入是预留的资源，所以不会冲突。而对于竞争的随机接入，网络侧会为每组第一资源配置对应的至少两个第二资源，以减少上行传输资源冲突的概率。
作为一个可选实施例，所述方法还包括：
接收网络侧设备配置的第二配置信息，所述第二配置信息为随机接入的第二消息的第二配置信息，所述第二消息包括：随机接入的消息B，或随机接入的消息2，或随机接入的消息4，或随机接入响应；
所述第二配置信息用于配置接收所述第二消息的响应窗和/或第三资源。
所述消息B，即为MSG B(Message B)，是两步随机接入的第二条消息。
所述消息2，即为MSG 2(Message 2)，是四步随机接入的第二条消息，或者两步随机接入的第二条消息的一部分，或两步随机接入回退四步随机接入的第二条消息。
所述随机接入响应，即为RAR(Random Access Response)。
需要说明的是，MSG2和/或MSG4构成两步随机接入的MSG B。上述MSG2是随机接入响应RAR；MSG4是竞争冲突解决消息或连接建立完成消息(如RRC建立消息、或RRC恢复消息、或RRC重建消息)。
例如，网络侧设备向终端发送第二配置信息，配置与每个第二资源对应的响应窗和/或第三资源。
进一步的，所述方法还包括：
所述终端在发送所述载荷使用的第二资源对应的响应窗和/或第三资源内接收所述第二消息。
进一步需要说明的是，上述接收第二消息的响应窗和/或第三资源与发送载荷的第二资源对应。例如，终端在第一个第二资源上发送载荷，则终端在与第一个第二资源对应的第一响应窗和/或第三资源上接收第二消息(MSG B或MSG 2)；再例如，终端在第二个第二资源上发送载荷，则终端在与第二个第二资源对应的第二响应窗和/或第三资源上接收第二消息(MSG B或MSG 2)。
简言之，UE接收MSG B或MSG 2的方法是：在与第二资源相对应的响应窗口或第三资源内接收MSG 2或MSG B。
综上，本公开的上述实施例通过为前导码的每组资源配置与其对应的载荷的多个资源，使得即使前导码发生冲突，网络侧也可以通过载荷的多个资源区分来自不同终端的消息A，提高载荷的解调概率以及终端的接入概率；同时MSG B的接收窗口是与MGS 3相对应的，可以最大程度避免MSG B的冲突。
如图3所示，本公开实施例还提供一种网络侧设备，包括存储器310、处理器300及存储在所述存储器310上并可在所述处理器300上运行的计算机程序，所述处理器300执行所述程序时实现如上所述的随机接入的资源配置方法。
综上，本公开的上述实施例通过为消息1的每组资源配置与其对应的消息3的多个资源，使得即使消息1发生冲突，网络侧也可以通过消息3的多个资源区分来自不同终端的消息A，提高消息3的解调概率以及终端的接入概率；同时MSG B的接收窗口是与MGS 3相对应的，可以最大程度避免MSG B的冲突。
